A trove of antiquities has been unearthed as the excavations for the Thessaloniki metro system continue, with recent discoveries of Christian period building remnants.

The most recent findings are at the Agia Sophia Metro Station. According to Voria.gr news website, archaeologists found a fountain structure at the southeast end of the marble-lined square, which came to light in earlier excavations of the spot, in the section above Egnatia Avenue.

The discovery originally made both construction engineers and archaeologists to stop works in order to discuss how to keep an ancient marble covered square and fountain system intact, while at the same time deliver the station on time and without exceeding the construction budget.
